- the foil element can preferably be arranged around a/the head part and/or between a/the closure cap and a/the basic body.
- the foil element can be realized such it blocks an axial movement between the head part and the basic body such that—as long as the foil element is attached—the ampule is not able to be broken.
- the foil element is then removed, as a result of which the blocking provided by the foil element is eliminated and the ampoule can be broken. If, for example, the foil element (label) is inscribed in a corresponding manner, intuitive and simple operation of the application pen can be achieved.

Abstract
Description
- The invention relates to an application pen for dispensing a liquid onto a surface, preferably for applying a protection layer onto adhesion surfaces of a vehicle, in particular for improving adhesion in the case of adhesive applications, said application pen including a hollow body, in which the liquid is received, preferably inside an ampoule which is received in the hollow body and can be broken for discharging the liquid.
- Pre-treatment agents for generating adhesive connections are usually provided in packages which consist of an aluminium bottle, polyethylene cup and a screw-type closure of the bottle produced from polyethylene. In the area of single-use applications, aluminium tubes or primer pens and activator pads, in each case with very little contents, are also provided
- Application pens of the above-described type are known, for example, from WO 2014/004521 A1. WO 2014/004521 A1 describes an application pen, including a cylindrical body in which a glass ampoule is held, an applicator part by means of which the liquid can be applied onto a surface as well as a closure cap. The ampoule is destroyed as a result of pressure being exerted radially onto the circumferential face of the applicator part such that the liquid is discharged from the ampoule. The applicator part includes a porous body for applying the liquid. A seal between the individual parts (cylindrical basic body, applicator part and cap) is effected by means of a press fit. Overall, in the case of the application pen according to WO 2014/004521 A1 there is the risk of the liquid drying such that said application pen can only be used multiple times (over a fairly long time period) with difficulty. In addition, the manner of the breaking of the ampoule is conceived as comparatively complicated and not very “intuitive”.
- The object underlying the invention, consequently, is to provide an improved application pen of the generic type which, in particular, is able to be used multiple times over a fairly long period of time and is simple to operate.
- Said object is achieved in particular by an application pen with the features of Claim 1.
- In particular, the object is achieved by an application pen for dispensing a liquid onto a surface, preferably for applying a protection layer onto adhesion surfaces of a vehicle, in particular for improving adhesion in the case of adhesive applications, said application pen including a hollow body for receiving the liquid in particular inside an ampoule (including a circumferential face) which is received in the hollow body, wherein the ampoule can be broken for discharging the liquid.
- According to a first independent aspect, a breaking device with an axially movable portion is provided and realized in such a manner that a movement of the movable portion in the axial direction results in the ampoule being broken. As a result, an intuitively easily understandable, simple and effective possibility for breaking the ampoule is created. The prior art proposes breaking devices which require force to be applied in a radial manner (for example as a result of crushing against a table edge or pressing in the circumferential face), which is conceived as comparatively complex and complicated. According to the invention, however, a breaking of the ampoule can be achieved in a comparatively simple manner as a result of introducing force in an axial manner (for example as a result of an impact onto an end of the application pen or as a result of a rotational drive by means of a thread, as explained in detail further below). An “axial” movement or introduction of force is to be understood as a movement or introduction of force in the direction of the longitudinal axis of the application pen.
- According to a second independent aspect (which can preferably be combined with the first aspect), the hollow body comprises at least two parts, preferably at least three parts, wherein a sealing ring, in particular a sealing lip, is provided on at least one face, in particular a circumferential face, of one of the parts, which is facing a face, in particular a circumferential face, of a further part. The sealing ring, in particular the sealing lip, is preferably integrally moulded on one of the facing faces. A “sealing ring” should provide a structure which is closed per se. A “sealing lip” is preferably a “sealing ring” which is realized as am annular lamella. A core concept of the second aspect consists in providing at least one sealing ring, which simplifies sealing of the individual constituent parts of the application pen. In particular, when the individual parts are movable (such as, for example, a closure cap in relation to a head part or a head part in relation to a base part, for example for breaking the ampoule), a high level of tightness is made possible with at the same time a comparatively simple relative movement.
- Overall, it is possible for more than one sealing ring, for example at least two, preferably at least three or four sealing rings (sealing lips) to be provided on one of the facing faces. For example, several sealing rings (sealing lips) can be provided on an outer circumferential face of a head part, a first group of sealing rings facing an inner face of a closure cap and a second group of sealing rings facing an inner circumferential face of a base part.
- According to a third independent aspect of the invention (which can preferably be combined with the first and/or second aspect), the hollow body includes at least one closure cap as well as a basic body, which preferably includes an end of the application pen which is remote from the closure cap, wherein the closure cap includes a liquid applicator part (in particular a liquid applicator felt), wherein the closure cap together with the liquid applicator part can be removed from the basic body, wherein the liquid applicator part, in the removed state of the closure cap, can be placed onto the surface, onto which the liquid is to be applied, for discharging the liquid. A core concept of the third aspect consist in that a liquid applicator part is arranged inside the closure cap and consequently the closure cap serves at the same time as a device for applying the liquid. In the prior art, for example in WO 2014/004521 A1, the liquid applicator part remains in the main body of the pen. The result of this is that when the liquid applicator part dries up, either the entire application pen has to be disposed of or (if this is at all possible) the liquid applicator part has to be removed as such out of the application pen, which is linked to a corresponding risk of contamination for the user. In contrast, the invention according to the third aspect allows for the cap including the liquid applicator part to be exchanged as one unit. As the cap represents only a relatively small or simply producible component, it is linked to only small costs and a slight impact on the environment. This generally results in the application pen being able to be used multiple times within a fairly long period of time.
- According to a fourth independent aspect of the invention (which can preferably be combined with the first and/or second and/or third aspect), the hollow body comprises at least one basic body and one head part, wherein the head part includes a (flexible) end face with a slot. The width of the slot can be no larger than 1 mm, preferably 0.5 mm, even further preferably no larger than 0.2 mm. In addition, the length of the slot can be at least 1.5 mm, preferably at least 2 mm or no longer than 10 mm, preferably no longer than 5 mm. A core concept of the fourth aspect consists in demonstrating an application possibility according to the “baby bottle” principle. In addition, a, where applicable transparent, closure cap can be provided. The head part can be produced from a (soft) plastics material, for example polyolefin (e.g. polyethylene and/or polypropylene) or from silicon. The head part is preferably realized such that it can be pressed-in in its front region such that the liquid can be dosed and applied as a result. The head part preferably does not comprise any felt and is therefore realized in a “felt-less” manner.
- In a preferred development, the movable portion is arranged and realized in such a manner that it can be moved in the axial direction as a result of an impact that is carried out in the axial direction onto an end of the application pen such that the ampoule breaks. The “impact” can be directed for example onto an end of the application pen which is located opposite the outlet region. The “impact” is preferably effected, however, onto an end at which the outlet region is arranged, for example onto a closure cap or a head part. An “impact” is to be understood in particular as a preferably short-term application of pressure, e.g. lasting less than 0.1 s.
- In an alternative further development, the movable portion can be driven as a result of rotation of a rotatable portion, in particular of a closure cap, such that a rotation of the rotatable portion drives the movable portion in the axial direction such that the ampoule breaks. The rotatable portion can be realized by the movable portion itself (at least in part). A corresponding rotary drive can be realized, for example, by a thread (screw-type thread). If the user then rotates the movable portion (or the rotatable portion) of the application pen, which is operatively connected to the movable portion, he drives the movable portion in the axial direction at the same time until the ampoule breaks. It is particularly preferred in this context when a closure cap can also be removed from the remaining components of the application pen by means of the same thread. For example, the movable portion (e.g. a head part) can be connected (operatively connected) to the closure cap. By means of a rotation of the closure cap, the movable portion can then be moved in the axial direction toward the ampoule such that said ampoule breaks. Once the ampoule has been broken, the closure cap can then be rotated in the opposite direction such that the closure cap can be removed from the remaining component parts of the application pen. All in all, a simple possibility for breaking the ampoule, which can be carried out without any great effort, is demonstrated by these types of measures.
- The breaking device preferably includes a deflecting device in such a manner that a force which acts axially on account of the movement of the movable portion is deflected in the direction of the circumferential face of the ampoule (for breaking the ampoule). In the case of an embodiment of this type therefore, on the one hand it is possible to break the ampoule by means of an axial movement (for example an impact from the front or the back) and this is combined in a synergistic manner such that by means of the deflecting device a force, which acts on account of the axial movement, is directed onto the circumferential face of the ampoule such that the ampoule is able to be broken with comparatively little expenditure of force.
- In a concrete embodiment, the breaking device includes at least one (preferably flexible) claw, preferably in such a manner that at least one claw is driven against the circumferential face of the ampoule as a result of the axial movement of the movable portion. As a result of this type of claw, the ampoule is able to be broken with comparatively little effort, which improves the operability of the application pen.
- The hollow body preferably comprises a head part and a basic body which includes an end remote from the outlet region. The head part is preferably movable in the axial direction in relation to the basic body. In said embodiment, the head part can define the movable portion or can realize at least part of the movable portion. In addition, the head part can realize at least one component part of the breaking device.
- In a concrete development, the head part is guided at least in portions inside the basic body. In a preferred development, the head part can comprise the above-described claw. The head part (just as the basic body) can be realized at least in portions in a cylindrical manner. The operability of the application pen is improved in particular when a relative movement between the head part and the basic body is utilized in order to break the ampoule (e.g. when an axial impact is presented).
- In one embodiment, a head part (in particular the above-described head part) can comprise at least one (porous) liquid absorption body, in particular at least one absorption sponge and/or one liquid applicator felt for applying the liquid. In the case of said embodiment, a closure cap, for example, is removed from the unit made up by the basic body and the head part such that a liquid applicator felt (in particular the liquid applicator felt) is accessible to the outside for applying the liquid. The absorption sponge can provide for absorbing vibrations during transport and, as a result, the ampoule is protected. In addition, it can provide for not allowing glass splinters to emerge in the front region when the ampoule is broken. All in all, the operability is simplified and injuries prevented as a result.
- The hollow body, (in particular a basic body of the hollow body), preferably comprises at least one run-up inclination on an inner circumferential face in such a manner that an axially acting force is converted, at least in part, into a radially inwardly directed force (directed onto the outer circumferential face of the ampoule). The run-up inclination preferably interacts with the claw which is described further above. Said claws, in turn, can also comprise a corresponding run-up inclination. All in all, a preferred embodiment is developed such that a run-up inclination of a claw interacts with a run-up inclination of the basic body such that an axial displacement of the claw in the direction of a rear end of the application pen forces the claw radially inward such that it presses against the ampoule and breaks it. All in all, a structurally simple solution to break the ampoule in a reliable manner is demonstrated as a result.
- In a concrete embodiment, a (removable) foil element, in particular a label, can be arranged around the application pen. The foil element can preferably be arranged around a/the head part and/or between a/the closure cap and a/the basic body. The foil element can be realized such it blocks an axial movement between the head part and the basic body such that—as long as the foil element is attached—the ampule is not able to be broken. In the case of a concrete application, the foil element is then removed, as a result of which the blocking provided by the foil element is eliminated and the ampoule can be broken. If, for example, the foil element (label) is inscribed in a corresponding manner, intuitive and simple operation of the application pen can be achieved.
- Generally speaking, the hollow body can comprise different parts, in particular a basic body, preferably including an end of the application pen remote from the outlet region and/or a head part (for example adjoining the basic body) and/or a closure cap.
- A liquid applicator part (in particular a liquid applicator felt) and/or sponge (absorption sponge) which prevents glass splinters of the ampoule escaping to the outside can be arranged inside the hollow body, as component parts of the application pen.
- The liquid applicator part, in particular the liquid applicator felt, can protrude at least in part from the closure cap, in particular by at least 2 mm or at least 4 mm. As a result, the liquid applicator part, in particular the liquid applicator felt, is accessible in a simple manner from the outside such that liquid can be applied onto a surface.
- The liquid applicator part can be connected (where applicable in a fixed and/or integral manner) to the cap, in particular plugged in and/or pressed in and/or glued on and/or welded on.
- An end of the closure cap remote from the liquid applicator part can comprise a recess. Said recess comprises, for example, a diameter of at least 0.5 cm and/or no larger than 1 cm and can comprise, for example, a round cross section. The closure cap can be gripped particularly easily as a result of a recess of this type such that the closure cap is able to be removed in a simple manner and in particular is able to function in a simple manner as a device for applying the liquid (with an integrated liquid applicator part). Operability is improved as a result.
- The closure cap can comprise axially extending ribs on its outer circumferential face. The operability of the cap, in particular when it functions as an applicator device for the liquid (with an integrated liquid applicator part) is also improved as a result.
- According to an independent aspect of the invention, a closure cap for an application pen, in particular of the afore-described type, is proposed, wherein the closure cap comprises an, in particular porous, liquid applicator part, preferably a liquid applicator felt.

FIG. 1 shows a schematic section of a first embodiment of an application pen. The application pen includes abase 10, an (axially movable) head part 11 (which realizes a movable portion) and aclosure cap 12. Thebasic body 10,head part 11 andclosure cap 12 define ahollow body 3. Thebasic body 10 comprises anend 14 of the application pen remote from the outlet region 13 (rear end). An ampoule 15 (shown by the broken lines) is arranged in thehollow body 13, specifically inside thebasic body 10 and (partially) inside thehead part 11. Asponge 16, which prevents the ampoule (or splinters thereof) being able to fall out of the application pen, is additionally provided. Thesponge 16 is provided inside thehead part 11. A liquid applicator felt 17 is arranged partially inside thehead part 11 and theclosure cap 12 according toFIG. 1 . Theampoule 15 can be broken by means of claws 18 (in the present example four claws are provided but this number is not compulsory) such that liquid is discharged from the ampoule. - The breaking of the ampoule is illustrated in particular in
FIGS. 2 and 3 .FIGS. 2 and 3 show an enlarged detail of the embodiment according toFIG. 1 in a first position (FIG. 2 ) and a second position (FIG. 3 ). It can be seen inFIG. 2 that anend stop 19 of thehead part 11 is removed from anend stop 20 of thebasic body 10 such that thehead part 11 andbase part 10 can be moved toward one another, which is symbolized by thearrows 21. If an impact is then exerted in the direction of thearrows 21 onto anend 22 of the application pen which is assigned to theoutlet region 13 and in the present case is formed by theclosure cap 12, thehead part 11 including thecap 12 is displaced in the direction of thebasic body 10. The end state is shown inFIG. 3 . During said movement, run-upinclinations 23 of theclaws 18 come into contact with a (ring-shaped circumferential) run-up inclination 24 of an inner circumferential face of the basic body such that the (flexible) claws are bent inward (in the radial direction) such that pressure is exerted onto the ampoule and it breaks (seeFIG. 3 ). The impact necessary to break the ampoule can be effected, for example, as a result of thebasic body 10 being gripped and thecap 12 being pushed (struck) head-on against a wall. - In order to make it easier for the
claws 18 to be able to bend radially inward, they are spaced apart from one another byslots 25. - Sealing between the
basic body 10 and the head part 11 (seeFIG. 3 ) is effected by means of sealingrings 26 which are provided on an outer circumferential face of thehead part 11 which is located opposite an inner circumferential face of thebasic body 10. Said sealing rings 26 achieve a high level of tightness without the mobility between thehead part 11 and thebasic body 10, which is necessary for breaking the ampoule, being excessively restricted. The cap 2 can be screw-connected to thehead part 11 by means of a screw-type thread 27 (the associated thread of the head part cannot be seen in the Figure as it is realized in an interrupted manner and the interruptions are in the section plane). Sealing of theclosure cap 12 in relation to thehead part 10 is effected by acone portion 28 on theclosure cap 12 and acone portion 29 on thehead part 11. In addition, thehead part 11 comprises an annularinclined face 30 which corresponds with thecone portion 28 of theclosure cap 12. In a similar manner, thecap 12 includes an annularinclined face 31 which corresponds with thecone portion 29 of thehead part 11. All in all, reliable sealing of thehead part 11 in relation to the cap 112 is realized as a result. - In
FIG. 4 thecap 12 is shown without thehead part 11 or thebasic body 10. As can be seen fromFIG. 4 , the liquid applicator felt 17 is arranged in arecess 32 of the cap (for example glued on or welded on or integrally moulded in another manner; where applicable, it is also possible for the liquid applicator felt 17 to be detachable from the cap). If, therefore, thecap 12 is removed from the remaining components of the application pen, thecap 12 still comprises the liquid applicator felt 17 associated with it, which is saturated with liquid on account of its previous contact with thesponge 16. Said liquid in the liquid applicator felt 17 can then be applied onto a surface. If the liquid applicator felt 17 has dried out or is no longer usable for another reason, thecap 12 can be thrown away and replaced by anew cap 12. In this case, the remaining components of the application pen can continue to be used. This increases the service life of the application pen in a considerable manner. -
FIG. 5 shows a schematic sectional view of a second embodiment of the (in a first position).FIG. 6 shows the embodiment according toFIG. 5 without the closure cap. The ampoule is not shown inFIGS. 5 and 6 for the sake of simplicity, however is arranged in an analogous manner toFIG. 1 . The mechanism for breaking the ampoule corresponds to the mechanism according toFIGS. 1 to 4 and is not explained again here. In contrast to the embodiment according toFIGS. 1 to 4 , nosponge 16 is provided in the embodiment according toFIGS. 5 to 7 . In the embodiment according toFIGS. 5 to 7 , the liquid applicator felt 17 prevents the glass splinters being able to escape from the ampoule. To this end, the liquid applicator felt 17 is not integrated in the cap 12 (cf.FIGS. 6 and 7 ) unlike in the embodiment according toFIGS. 1 to 4 , but in thehead part 11. Analogous to the embodiment according toFIGS. 1 to 4 , thehead part 11 is sealed in relation to thebasic body 10 by sealingrings 26. Said sealing rings 26 can be realized as sealing lips or sealing lamellae. In addition, an outer circumferential face of thehead part 11, which is located opposite an inner circumferential face of thecap 12, also comprises sealing rings 33 a to 33 c. The sealing ring 33 a (seeFIG. 7 ) engages in a corresponding ring-shaped recess (groove) 34 on an inner circumferential face of thecap 12 for realizing a latching connection. The sealing rings 33 b, 33 c are realized as sealing lips (sealing lamellae) which improve the sealing further. Thecap 12 according to the embodiment according toFIGS. 5 to 7 is fitted onto thehead part 11, a connection being realized as a result of latching. -
FIG. 8 shows a schematic sectional view of a third embodiment of the application pen. The third embodiment according toFIGS. 8 and 9 corresponds to the first embodiment according toFIGS. 1 to 4 (in particular with regard to the sealing between thehead part 11 and thebasic body 10 or thehead part 11 and theclosure cap 12 as well as with regard to the liquid applicator felt 7 and the sponge 16) with the following differences. In the case of the embodiment according toFIGS. 8 and 9 , theampoule 15 is broken by a ring-shaped constriction which provides a predetermined bending point. On account of the ring-shapedconstriction 35, thebasic body 10 can be bent such that theampoule 15 breaks. As can be seen inFIG. 9 , the liquid applicator felt 17 is arranged inside theclosure cap 12 in the case of the third embodiment analogous toFIG. 4 . -
FIGS. 10 and 11 show a schematic sectional view of a detail of a fourth embodiment of the invention. The parts of the fourth embodiment not shown, in particular in so far as this relates to thebasic body 10 and the mechanism of the breaking of the ampoule, can be realized as in the first, second or third embodiment (or in a combination of said embodiments). In contrast to the preceding embodiments, no liquid applicator felt is provided in the embodiment according toFIGS. 10 and 11 . Splinters are prevented from falling out of the ampoule by thesponge 16 which additionally sucks up and absorbs liquid. In order to be able to use the application pen according toFIGS. 10 and 11 , first of all the (preferably transparent)cap 12 has to be removed (seeFIG. 11 ). As a result of pressing onto acircumferential face 36 of thehead part 11 in the region of thesponge 16, liquid is ejected through aslot 37 according to the “baby bottle” principle. The sealing between thehead part 11 and thebasic body 10 is effected by means of sealinglips 26, as in the embodiment according toFIGS. 1 to 4 . Thecap 12 is sealed in relation to thehead part 11 by means of sealing rings 38 a, 38 b, the sealing ring 38 a engaging in a corresponding annular groove 39 on an inner circumferential face of thecap 12 for realizing a latching connection. The sealing ring 38 b is realized as a protruding sealing lamella. -
FIGS. 12 and 13 show sectional views of a fifth embodiment of the invention (FIG. 12 with closure cap;FIG. 13 without closure cap). The mechanism of breaking the ampoule corresponds to the mechanism as is described in the case of the embodiment according toFIGS. 8 and 9 . A sponge is not provided, but rather a liquid applicator felt 17. Analogous to the embodiment according toFIGS. 5 and 6 , said liquid applicator felt remains in thehead part 11 which comprises sealinglips 26 analogously to the preceding embodiments in order to realize sealing between thebasic body 10 and thehead part 11. In addition, analogously to the embodiment according toFIGS. 5 to 7 , sealing rings 33 a to 33 c are provided in order to enable latching of theclosure cap 12 as well as sealing between theclosure cap 12 and thehead part 11. - In the embodiment according to
FIGS. 1 to 4 as well as 5 to 7, a circumferential foil element (not shown) can be arranged preferably as a label in a region between the end stops 19 and 20 (seeFIG. 2 ). If this label is removed, the end stops 19 and 20 are able to be moved toward one another. - In principle, in the case of all the embodiments (where applicable with structural adaptations) the
respective cap 12 can be screw-connected or fitted (positioned) onto thehead part 11. - The
sponge 16 can be, for example, a melamine sponge or can be produced from another plastics material. In general, thesponge 16 can be formed from a foam material. Theampoule 15 can consist, for example, of glass. The basic body and/or the head part and/or theclosure cap 12 can be formed from a plastics material, for example polyamide, polyethylene or polypropylene (generally polyolefin). - In principle, the application pen is used for applying liquids onto all types of surfaces. A preferred application is the applying of a liquid as an adhesion-promoting substrate or as a protection layer in the region of connecting faces (for example in the automobile sector when inserting panes).
- The liquid applicator felt 17 can generally be an arbitrary liquid applicator part. The liquid applicator felt can consist of fibres that are randomly arranged or of fibres that are aligned in the direction of the fluid.
-
FIGS. 14 and 15 each show a detail of a sixth embodiment of the application pen.FIG. 14 , in this case, shows a detail analogous toFIG. 2 .FIG. 15 shows a detail analogous toFIG. 3 . In contrast to the embodiment according toFIGS. 2 and 3 , the head part 11 (the movable portion) is not moved by means of an axially acting impact, but by a rotation of thecap 12. To this end, thecap 12 comprises a thread 40 (which is preferably realized as an internal thread). Thebasic body 10 comprises s corresponding thread 41 (which is preferably realized an external thread) such that theclosure cap 12 can be moved by rotation in the direction of thebasic body 10. As a result, thehead part 11 is also urged in the direction of thebasic body 10 such that the run-up inclination 23 of thehead part 11, analogous to the embodiment ofFIGS. 2 and 3 , runs up against the run-up inclination 24 of thebasic body 10 such that theclaws 18 are pressed inward and an ampoule, located between the claws 18 (not shown inFIGS. 14 and 15 ; cf. for example,FIG. 1 ), breaks. In addition, in the embodiment according toFIGS. 14 and 15 ,positioning journals 42 are still provided between the liquid applicator felt 17 and the ampoule (not shown inFIGS. 14 and 15 ) such that the ampoule can be positioned and supported before it is broken. - Apart from this, sealing rings (or sealing lips) 43 are provided between the
head 11 and thebasic body 10. -
